If you keep a clear record of who you spoke with along with the info they provided you have at least done some due diligence in getting an answer from the agencies that are charged with enforcing these laws..

When I moved back to Oklahoma, I had a CCW permit from a state that allowed me to change it to a non-resident permit, so it was still good for 3 or 4 years. I used the email on the OSBI website to confirm that Oklahoma recognized the non-resident permit. I kept a copy of the email with me in case I ever needed to explain why I had an Oklahoma DL and another state CCW permit. I used the email specifically so I would have a paper/electronic trail, not just I spoke to someone (maybe the janitor) at OSBI and they said it was OK.
Here is the link to ask OSBI a question. I got a response in about 24 hours. http://www.ok.gov/triton/contact.php?ac=168&id=144
